It will, but it will take much longer than a 12V 5A supply because it will not be able to provide sufficient amperage. When I was chargin the battery w/ my power supply I was reading 4.5 amps.
well, with a 12 volt battery will i need 15v iv been on google and some sites say charge it a 15v. 12v will not put anything through, my multimetre says 0A, when i charge a 6v battery at 8 volts it works.
yea i have 2, 1 6V one. 1 12V one. the 6V charges fine at 8V. at the moment my power supply will only go up to 12V and that is not charging the 12V battery. i only want a trickle, i don't want to destroy them.
You should be perfectly safe charging the 12V @ 13-15V. The battery in my truck is charged to 14V. Yes, do as willib said and check the voltage on the 12v battery. If it is already at 12v and you try and charge it with 12v it won't do anything at all.
most dumb chargers , built for Ni-Cads or NiMH batteries , will continue charging them well after they are " done ".. making them very hot and ultimately destroying them..
Lithium and Magnesium are never safe.
The Brits sent battleships down to fight the Falkland Islands war. The ships were made of magnesium and caught on fire!
They didn't burn when they were wet on their journey down there.
The dead Li-Ion battery from my son's laptop is crammed full of electronics to prevent over-charging that will set it on fire. :lol:
Sorry, I watched American news reports showing a faulty missle piercing the magnesium skin of the battleship which set it on fire. Some missles went completely though the flimsy ship and out the other side, setting both sides on fire.
Reminds me of the flimsy Japanese Zero planes (made from rice-paper?) that were faster and could climb steeper than the American heavier ones. When a Zero went into a steep dive, it fell apart. Many times you see a film clip from an American plane chasing a Zero, and the Zero blows-up before even being shot at. :lol:
